TOOL-HOLDER.

Specification of Letters Patent. Patented May 22, 1917.:

Application filed November 28, 1916. Seria1 No.'133,9o 1.

To all whom it may concern:

Be it known that I, ALBERTO P1 33132 DE VILLA-AMIL, a citizen of Cuba, and a resident of Cienfuegos, Cuba, have invented a new and Improved ToolHolder, of which the following is a full, clear, and exact description.

My invention relates to means for holding tools of various kinds for the grinding of the tools, such as chisels, plane irons, gouges, knives, etc.

A general object of the invention is to provide a holder adapted to be connected with a support on a grindstone frame or the like, and having means for holding various tools, as Well as means for variously adjusting the tool to properly present the same to the grindstone.

The invention also has for its object to improve tool holders of the indicated character in various particulars whereby to promote convenience and accuracy ofadjustment and control.

The nature of the invention and its advantages will clearly appear as the desciption proceeds.

Reference is to be had to the. accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views.

Fig. 14 is a longitudinal vertical section on the line 1 11 1, Fig. 13 1 Fig. 15 is an inverted plan view of the tool carrier shown in Figs. 13 and 14;

Fig. 16 is a fragmentary side elevation of a tool-clamping device.

Referring more particularly to Figs. 1 to 12, my improved tool. holder includes an elongated bar 10 provided with a suitable handle 10 and formed with a longitudinal slot 11 extending from near the handle to the front end. In the slot of the bar 10 is received an extension bar 12 to varythe efiective length of the bar.

On the frontendat the extension bar 12'is:

a swiveled ring 13 whi'chis adapted to be engaged with a hook 1 1 on a standard 15 whichis suitably fastened to the frame A of'a grindstone' which here is shown as having a crank handle B to be turned by hand or by a connecting rod C connecting said handle with a treadle (not shown).

The ring 13 is swiveled to the extension bar 12, as best shown in Fig. 8, by a rivet 16 which extends" through an end cap or ferrule 17 suitably secured to said baras.

by screws :18. The rivet 16 has a washer 19 and at the inner side of the same is a plate 20 against which a. compression spring 20 bears at its front end, said spring being suitably housed in the end of the extension bar 12 beneath the cap 17. The spring serves to exert a sufficient friction between the plate 20 and the washer 19 to hold the ring 13 in adjusted position.

To holdthe extension bar 12 in adjusted position relatively to ,themain bar 10, a keeper 21 in the form of a rectangular sleeve is provided on the bar 10,.and suitably se-.

shown a head 22 for the purpose; The ex;

tension bar 12 is retained and guided at its inner end on the bar 10 by means of upper and lower plates 24 secured to said extension bar by screws 25, or the like, and overlapping the sides of the said bar 10.

On the bar 10 is slidably fitted a carriage designated generally by the numeral 26 which is grooved at its upper side as at 27 (Fig. 5) to receivethe slotted bar 10. To retain the carriage on the bar, a rear plate 28 is secured to the carriage 26 at each side of the groove 27 and bridges said slot. The plate is secured by screws 29. Also, a front plate 30 is secured to the carriage 26 at each side of groove 27 by screws 31 and bridges the slot 11 at the front of the carriage.

Transverse bolts 32, having nuts 33, ex-

tend through the carriage 26 and on these bolts there is suspended a tool receiving and seating element- 34 through the medium of side plates 35 secured to element 34 by screws 36, or the like, and secured to the carriage 26 by the bolts 32. In order to provide for varying the angular position of the element 34 on the carriage 26 and relatively to the plane of the bar 10, the side plates 35 are formed with slots 37 which are oppositely inclined, the front slot 37 inclining rearwardly from its lower end and the rear slot 37 inclining forwardly from its lower end. At the lower ends of the slots 37 are complementary recesses 38, the recesses in the respective slots being oppositely disposed, the forward recess 38 being in the front wall of the adjacent slot 37 while the rear recess 38 is in the rear wall of the adjacent slot 37. Similarly, at the upper ends of the opposed walls of the slots 37, recesses 39 are formed complementary to said slots, and between the recesses 38 and 39, there are formed in the opposed walls of the slots intermediate recesses 40. Thus. by loosening the nuts 33 of the bolts 32, the element 34 and the plate 35 may be rocked in a vertical plane either forwardly or backwardly and the plates manipulated to dispose the bolt 32 in either of the recesses 38, 39, or 40. Thus, various angular positions may be given to the element 34 to properly position the tool D relatively to the grindstone.

On the under side of the element 34, front and rear wear plates 41, 42 are provided and secured by screws or other means. As best seen in Figs. 3 and 4, the under side of the element 34 at the rear is formed with a depression 43 and the wear plate 42 is formed with a corresponding opening 44 to accommodate the forward end of a handle or ferrule of the tool D (see Fig. 4) when the tool is of a character to require the pro vision of said depression 43.

To secure the tool to the under side of the threaded shank extending upwardly through the said element 34, through the carriage 26 and slot 11, the shank being provided with a wing nut 48 at its upper end. The lower end of the tool clamp 46 has an opening 49 suitable for the particular tool being ground. A variant of the gripping device is shown in Fig. 16, it being designated generally by the character 46*. Said clamp has a threaded shank 47 corresponding with the shank 47 and an opening 49 of a form to properly clamp the gouge indicated at D. The swiveling of the ring 13 facilitates the grinding of the transversely curved edge of a gouge.

In Figs. 11 and 12 a plane iron or knife D is shown secured to the tool receiving element 34 by a clamping device 46 the lower end of which is in the form of an inverted T-head which is adapted to be passed through the usual slot of the plane iron and then given a quarter turn to dispose the T-head transversely of the said iron. The threaded shank 47 of the gripping device, Figs. 11 and 12, is provided with a wing nut 48 I In order that the element 34 may have clearance in its rocking movements in a vertica-l plane relatively to the tool clamp 46, etc., the said element is formed with an upwardly flaring opening 50 in register with a suitable vertical opening 51 in the carriage 26. In addition to the openings 50, 51, auxiliary vertical openings 52, 53 are formed in the element 34 and carriage 26, respectively, in front of the first mentioned opening, and said openings 52, 53 may receive the clamp 46". A detail also, of the tool holder, it will be observed, is the provision of. a recess- 59 in the plate 30 to accommodate the washer provided beneath the nut 48 of the tool clamp 46 when the tool clamp is placed in the openings 52, 53.

To prevent the bolts 32 from turning when the wing nuts 33 are turned, the shanks of said bolts are each formed With a lateral lug 54 which are received in a recess 55 in the adjacent side of the carriage 26, there being a complementary slot 56 in the washer 57 on said bolt and a registering slot 58 in the adjacent side plate 35, said slots permitting the lug 54 to be entered in and withdrawn from the slot 55 with the entrance and removal of the bolt.

In the modified construction illustrated in Figs. 13 to 15, provision is made for swiveling the tool receiving element on the carriage. In this form the carriage designated generally by the character 26 presents upswiveled to the carriage to turn in its own plane, that is to say, in a plane parallel with the bar 10. The arms26 of the carriage at their upper ends are offset horizontally in opposite directions as at 26 and receive turn-buttons 26 so that by giving the buttons a quarter turn they may be disposed end to embrace the round handle of a knife D for disposing the knife transversely or approximately so to the bar 10. The clamp 46 has a shank 47 receiving a wing nut 48, the shank having also a washer 6O bridging the slot 11. The tool clamp A6 is accommodated in a vertical opening 50 in the element 34:, said opening being in register with a contracted opening 50 accommodating the shank 4:7. The swiveled base 26 of the carriage 26" has a registering ver-. tical central bore 26 through which the shank 47 passes. In this form of the invention also, the wear plates 41*, 42 are applied to the under side of the element 34 Between the plates 42 the carrier 3 is provided with a depression 43 to accommodate the round handle of a knife, D
